g is also affected by the fact that the Earth rotates and an observer on its surface therefore experiences a centrifugal force. We can summarise by saying: (1) If the Earth were a non-rotating perfect sphere, the acceleration due to gravity would be constant. (2) Because of rotation, the Earth is flattened at poles. This affects g in two ways:-
Multifocal motor neuropathy (MMN) is a disease that affects your body's motor nerves. Those are the nerves that control your muscles.
Lower motor neurons, or second order neurons are cranial and spinal nerves. The cell bodies of these neurons are located in the brain stem, but their axons can leave the central nervous system and synapse with the muscles of the body.t the level of the lower motor neurons, there is no alternative route which will allow messages from the brain to reach the periphery. Muscles on the same side of the body as the lesion will be affected. Lesions on the cranial nerve nuclei located in the brain stem are called bulbar lesions.
